ATTACHMENT FRAME FOR MOBILE UNITS.

Original No. 1,653,020, dated December 20, 1927, Serial No. 52,562, filed August 26, 1925.

for reissue filed October 27, 192. Serial No. 315,573.

This invention relates generally to mobile units, that is to say, units adapted to some useful purpose while capable of propulsion under their own power from place to place, in contradistinction to those now commonly known as portable units, or which involve trailing from one sphere of operation to another. Units of the character first mentioned are of diversified types, but usually embody some utility and a source of propulsive power, said utility being operated by the source of power when the latter is disconnected or not engaged in transportation.

An object of this invention is to provide an attachment frame for rigid connection to a motive unitsuch as a tractor for example which is so designed as to ensure a non-vibratory support for the utility adapted for operation by the motive unit when not engaged inpropulsion or travelling from place to place.

Another object of this invention is the provision of an attachment frame component characterized by great strength and ease of connection or disconnection to the crank case and rear axle housings of standard types of tractors whereby said tractors are adapted to include a work utility or the like and operate the same with maximum economy.

A further object of this invention is the cheap and economical conversion of standard tractors into mobile units including one or more utilities adapted for operation thereby.

With the foregoing and other objects in View, which will be apparent from the following description, this invention essentially consists of the matters hereinafter set forth, typically exemplified in the accompanying sheets of drawings, and circumscribed as to subject matter and scope by the appended claims.

In the drawings:

Figure 1 is a. top plan view of my novel attachment frame as adapted to a standard type of tractor, a portion whereof is fragmentarily shown, while the associated utility is indicated diagrammatically by dot-anddash outline so as not to confuse the illustration;

Figure 2 isa side elevation of the preceding figure;

Figure 3 is a perspective view of the attachment frame with minor parts broken away for the sake of clearness; and,

Application Figure 4 is a fragmentary detail of a portion of the attachment frame, later on fully explained.

For the sake of practical explanation as to one convenient application of the present invcntion I have elected-by way of example onlyto describe the same as adapted to a mobile compressor unit, but it is to be distinctly understood that I am in no sense limited thereby.

Referring more specifically to the drawings, on which like reference numerals are applied to corresponding parts in all the views. it will be observed that the rear portion of a standard type of tractor is comprehensively designated 5, while the numeral 6 indicates the rear axle housings. 7 is the steering wheel, 8 the operators seat, 9 the foot brake, 10 the gear shift, 11 the clutch A control, and 12 the lever which connects or disconnects the compressor 13, as later on explained. The rear wheels .of the tractor 5, are designated 14 while a portion of the fuel tank is shown at 15. As the foregoing parts are old and well known, further explanation thereof is deemed unnecessary herein, and they are but briefly enumerated as essential to a full comprehension of my invention, now to be described in detail.

As best appreciated from Figure 3, it will be noted that, in the main, this invention comprises a framework attachment, comprehensively designated 16, and comprising opposed side units 17, 18, detachably connected at their rear ends by a transverse member 19. Each side unit17, 18, it will be seen, consists, conveniently though not essentially, of a standard I-beam or longitudinal 20, that is cut away and shaped as later on fully explained, with a sub-plate 21 welded to the fore basal flanges thereof at 22, as well as rigidly united by spot weldings 23, through said basal flanges at each side of the web thereof. These sub-plates 21, it is to be par ticularly remarked, thus become incorporated base flanges of the I-beains 20 and they are configured to snugly conform to the crank case 24 of the tractor 5. In addition to the foregoing, the sub-plates 21 are provided with a series of holes 25 adj acentthei'r inner edges for substitute bolt-s 26-Figure 1-which pass through the ordinary flange holes of the crank are rigidly supported and connected to the tractor 5 in a manner effectively precluding any tendency to lateral or other displacement while affording rearwardly extending stable support for the compressor 13.

In order to rigidly brace the side units 17,

18 against vertical deflection, I weld obliquely disposed angles or channels 30 to the lower rear flanges of the I-beams 20 at 31; said angles or channels 30 being cut away and shaped at their forward ends to provide eyepieces 32 which are bolted or otherwise secured at 33 to the flange of the juxtapositioned axle housing 6, as clearly shown in Figure 2. Attention is also directed to the fact that I additionally unite the brace members 30 rigidly to the base flanges of the I- beams 20 by spot weldings 34--Figure 3.

By so welding the brace members 30 to the longitudinals 20, I provide in effect a horizontally disposed unitary frame assembly adapted to be secured to the tractor unit in rearwardly extending relation with respect thereto, it being particularly noted that this assembly is of generally U-shape having side sections each of which latter is characterized by the provision of upper and lower portlons converging toward the rear end of the assembly. By reason of the fact that the divergent fore ends of these portions of each side section are respectively provided with vertically spaced means for securing said ends to corresponding spaced parts of the tractor unit, there is effectually precluded all tendency for the frame assembly to vibrate in a vertical direction when said assembly is connected to the tractor. It will be understood, of course, that the invention is not limited to the particular means herein shown and described for connecting said divergent fore ends of each side section to the tractor unit and that any other equivalent means may be employed with equal effectiveness.

Referring now to the rear transverse member 19, the same is conveniently cut from a standard channel section to snugly seat at 35-Figure 3bet\\'ecn the upper and lower flanges of the I-beams 20, and it has angle clips 36Figure 4welded thereto by means of which it is secured in place between the side units 17, 18 through the medium of bolts 37 Thus it will be readily seen that the side units 17, 18 are transversely braced in a rigid manner at their rear ends, and thereby afford a secure bearing for the compressor 13 which is mounted thereon and secured in place by bolts 38Figure 2p assin g through holes 39 in the top flanges of the I-beams 20- Figure 3. Obviously additional transverse channels may be fitted at intervals intermediate the side units 17, 18 where deemed necessarv. As the specific form of unit illustrated involves a storage tank 40 for the compressed air produced by the compressor 13, I afford chock spacers therefor in the form of transversely disposed angle irons 41, 42 of suflicient length. These angle irons 41, 42, it will be seen, extend beyond the side lines of the attachment frame 16, and the former 41 is integrally welded at 43 to the top flange'of the transverse member 19, While the latter has angle clip 44 welded thereto with provision for bolting connection 45 to the aforesaid I- beams 20. as will be readily understood. The storage tank is secured to the chock spacers 41, 42 by removable straps 46 and bolts 47, in the well known manner. I

From the foregoing it will be seen that the attachment frame 16 extends rearwardly from the tractor 5, and that it forms and constitutes a rigid support for the compressor 13 which is operated by a direct drive connecting shaft 48Figure 2from the tr'actor transmission, and that it can be connected or disconnected from operation therefrom by the lever 12, aforesaid.

From the foregoing description, taken in connection with the accompanying drawings, the construction and manner of mounting or dismantling my novel attachment frame will be well understood without further detailed explanation, while its ready adaptability for compact shipment is self evident. Furthermore, changes in the form, proportions and minor details, obviously, may be made within the scope of my invention without departing from the spirit or sacrificing any of the advantages thereof, particularly in so far as the cutting away of the I-beam20flanges is concerned to conform to different types of prime movers, as well as to accommodate other utilities than that specifically illustrated.
